Abstract—Lakes in Universitas Indonesia (UI) have several
problems to overcome. Water quality of UI’s lakes degrades in
the last decade. One of the problems is high turbidity. The
longer turbidity in lakes, the more dangerous the lakes
environment life would be. So, this research focuses on
sediments problem or physical assessment. The main research
aims to develop hydrodynamic and sediment transport
modelling of Agathis and Mahoni Lakes in Universitas
Indonesia. The authors want to increase the quality of water in
UI’s lakes and make both Agathis and Mahoni Lakes as the
representative preliminary model. Research design or
methodology is needed to concept the research to achieve goals.
Unfortunately, research methodology has not been developed
yet for this case. This paper goals to construct methodology as a
preliminary study of the main research. The authors use
extensive literature review to model novel methodology.
Hydrodynamic and sediment transport modelling could be
modelled by Resources Modelling Associates (RMA).
Hydrodynamic phenomena in fluid and sediment transport
modelling have the suitable governing equation concept with
RMA’s governing equation. As a thinking result, the main
research would be conducted by RMA program modelling, field
sampling, and laboratory testing. Field sampling and
laboratory could figure the amount of sediment concentration
in lakes as data input. The final simulation of this following
research is making sensitivity and scenario analysis to prove
several hypotheses.
